We used low rf power probing in films thinner than the London penetration depth $\\lambda(B)$ to significantly increase the field onset of vortex penetration and measure the NLME under equilibrium conditions. Contrary to the conventional quadratic increase of $\\lambda(B)$ with $B$ expected in s-wave superconductors, we observed a nearly linear increase of the penetration depth with $B$.
